il'ni'rrnD Sfrn'rns LEONARD J. wonDEN, oF UTIGA, NEW YORK- iMPaovEMENT IN CAST-IRON Bottoms-'Foa TEA-KETTLES.

Specification forming part of Letters Patent No. 38,7%), dated June 2, 1863.

To all whom it may concern,.-

Beit known that I, LEONARD J. WORDEN,

of New York, have invented a new and Improved Mode of Constructing Cast-Iron Bot toms for Sheet-Metal Vessels; and I do here by declare that the following is a full and exact description thereof, reference beingr had. t0 the accompanyingdrawings, and to the let- The nature of my invention consists in prov idin g a cast-iron bottom for tea-kettles, washboiler's, and other sheet-metal vessels, which,

mode' of connection, forms a superior article of manufacture.

To enable others skilledin the art to make and use my'invention, I will proceed to de- Figure l is a perspective view of a tea-kettle with one-half the bottom cut away to show its f construction.

A represents the cast-iron bottom; B, a narl row rim or band of' sheet metal; C, a raised proi jection of the bottom cast to and around the lower edge ofthe band, so as to unite and form a water-tight joint. The cylinder part ot' the vessel D is then placed over and outside the band B and connected together by soldering on the inside, with or without a seam; or, if prei'erred, the cast-iron Abottom may be cast to l and around 'the llower edge of the cylinder composing the body of the vessel, as shown in the transverse sectional View at A, Fig. 2, forming only one piece Without any soldering, which is simply a wide band, instead of the l na-rrow, extending upward sufficiently high to form the .side or body of the vessel, either way making a perfectly water-tight joint.

Itis evident that this method yof making cast-iron bottoms may be applied tofany of the various kinds of sheet metal that can be used in constructing either the body of the vessel or narrow band. when unitedwwith the bottoms as described;I also, that the cylinder or body of the vessel maybe placed either outside or insideof the band without changing the nature of the invention.

Having thus described my invention, lits advantages over the common mode will be apparent, in lthat it enables me to substitute east-iron for copper and other expensive sheet metal, thus reducing the cost of manufacture, while I am enabled to produce a better and more durable article than has heretofore been made. A

I ain aware that coascuttles have been made with cast-iron bottoms by riveting the parts together. I do not, therefore, broadly claim a castiron bottom for sheet-metal vessels, neither do I claim uniting or casting two metals together, as in the case of' anvils, 'vise l 'aws frogs for railroads ear-wheels &c. but

I claim as a new article of manufacture- Making the bottoms of tea-liettles ot castiron by uniting it to and with the body of the vessel in the manner and for the purpose as herein described and set forth.
